at the international trading environment and worry about that. this is the answer to your question. a world and which the united states is strong but all of the institutions is eroding is not a world of 2011. the united states has an interest in trying its best to shore up institutions. >> this is great. >> get set to run it, john. >> a couple of quick points. my thesis is not the institutions are independent. they are instruments of power. they are used to signal limits on power. power is never divorce from institution. a venture that regard, i idea that the united states has been so brilliant for half a century or longer because, it has allowed it to make the power more durable and expensive but also making it more delimited and less based on arbitrary use of power and the most traditional sense. there are a vehemence of republican allow for the state to be more influential by allowing it to signal its own strength. a couple of more point about this. my underlying argument is that we are shifting from one organized around trilateral world, the u.s. rip germany, japan, the kind of trilateral system.
